On the Repetition of Medicines

The dose may be repeated with the best, often with incredibly good results, at intervals of fourteen, twelve, ten, eight, seven days in chronic diseases resembling acute diseases, at still shorter intervals; but in acute diseases at very much briefer periods….

Hahnemann at first gave repeated doses-Instances of his repetitions-He afterwards attempted to regulate the repetition by the supposed duration of action of the medicine-Afterwards his rules was that the medicine should not be replaced as long as improvement went on-Difficulty of following Hahnemann’s rule-The medicine has not exhausted its action until improvement stops-He next allows the medicine to be repeated before it has exhausted its action-He allows the rapidity of the course of the disease to determine the repetition-The medicine when repeated must be given in a lower dilutions-He latterly allowed the medicine to be repeated very frequently, even in chronic diseases-But each time in a different potency-AEgidi asserts the advantage of more frequent repetition-Wolf advises more frequent repetition-Hering enumerates cases where repetition is useful-Gross and Kretschmar advise repetition in certain cases-Rau attempts to show when repetitions are useful, when hurtful-Kampfer’s rules for the repetition- Attomyr looks to the provings for the rules for the repetition-Attomyr’s un-Hahnemannic directions-Koch’s rules- Griesselich’s laudation of repetition-Circumstances in which it is to be employed-Periods of exacerbation of the disease ought to regulate the repetition-Trinks’s rules for the repetition- Arnold’s maxims-Attempt at a rule for the repetition in acute and chronic diseases-The exacerbations, periodicity, and rapidity of diseases should regulate the repetition-The dose cannot guide us in the repetition-Some homoeopathists contend for rare repetition, though Hahnemann latterly renounced the practice.

THEORETICALLY it might be inferred that the proper remedy having been discovered for the disease, and the appropriate dose having been found, all that remained for the physician to do was to place this dose of this remedy on the patient’s tongue, and this would amply suffice to effect the cure of the disease. Such a priori reasoning is encouraged by various parts of Hahnemann’s teachings, especially during the latter period of his life; thus his teaching in the Organon is that the dose of the appropriate medicine cannot be too small, so that it shall not be stronger than the disease to which it has a homoeopathic relation, and the logical inference from this of course is, that one single dose of one remedy is quite enough in acute as well as chronic diseases; and according we find this to have been Hahnemann’s doctrine and practice at one period.

But I am anticipating. This subject, like the others that I have in former lectures brought under your consideration, I shall proceed to consider historically, that is, I shall give you Hahnemann’s first practice, as far as that can be learned from his writings, and trace its gradual development in his mind, showing you the modifications his views and practice underwent with the growth of his system, and pointing out the circumstances that influenced his practice with respect to the repetition of the same medicine.

In the first essay he wrote announcing the discovery of the homoeopathic law in 1796, (Lesser Writings, p.295.) we find him giving the homoeopathic medicines–in considerable doses, as I formerly showed–very much in the same manner as the ordinary practitioners adopted, to wit, once or twice a day, in maladies of a chronic character. The case of colicodynia treated by him in the same year (Lesser Writings, p.353.) got the remedy also every day, but even at this period of his career he was conscious of what is called the cumulative action of certain medicines, such as digitalis and arsenic, and enjoined caution in their repetition. As regards the former of these medicines, he distinctly states (Ibid., p.328.) that its action lasts several days, and that therefore it might be attended with dangerous consequences to repeat the administration of even a small dose of it oftener than every two or three days, and he mentions a case where death ensued in consequence of giving only two grains of digitalis three times a day for three successive days; the effect in this case, he adds, in consequence of the long duration of the action of digitalis, was as if the whole eighteen grains had been administered at once.

In the two essays on intermittent and periodical diseases, published in the course of the following year 1798, (Ibid., pp.382,395.) no noteworthy difference is observable in his repetition of the medicines from what obtained and still obtains in the ordinary practice; thus six or seven grains of ledum, three times a day, is a prescription he used with success in a chronic affection remaining after the subsidence of a sort of remitting fever, and cinchona bark, half a drachm, twice a day, is what he gave in a case of intermitting asthma. It is not until we come to his treatment of scarlet fever that we find an attempt made to regulate the repetition of the remedy by its supposed duration of action. Thus the action of belladonna is supposed to last three days, (Ibid., p.437.) and its repetition for prophylactic as well as for curative purposes is enjoined to be made not oftener than every seventy-two hours as a general rule, excepting when the virulence of the disease is very great, when shorter intervals of repetition are recommended. That, however, Hahnemann did not yet consider the exhaustion of the action of the medicine should be waited for before giving another dose is evident from another passage in this essay on Scarlet Fever, where he directs a dose of belladonna every three hours, for the purpose of suppressing the disease when it first breaks out. (Ibid., p.441.)
